Jim Martin...I don't think I said you were a troll, just trying to answer your question!!
It's not easy to understand the useage of words on T'Net sometimes. But trolls are pretty easy to suss out after a while!
When spotted, best ignore. Just as I am on this thread, (although, being human, it's sometimes very tempting to bait them, never worked though, it just encorages them)
For instance, I think the originator of this thread was either a troll or something else. It has been shown by the owners of the site, that two posters here are contributing from the same computer. Draw your own conclusion, and then ignore.
Or not....whichever you find most fun, I suppose!
